    Abstract: Disclosed herein are a variety of embodiments of a thermal interface material that may be used in a variety of systems and methods to improve heat transfer. One embodiment consistent with the present disclosure includes a heat dissipation system that includes a heat source and a heat sink. A thermal interface material may be at least partially disposed between the heat source and the heat sink. The thermal interface material may include a plurality of strands of thermally conductive material woven into a pattern. The thermal interface material may be configured to conform to the contact surfaces of the heat source and the heat sink to thereby increase transference of heat between the heat source and the heat sink.

    Abstract: A thermal interface member may comprise a substrate having a first surface and an opposite second surface, an electrically conductive layer disposed on the first surface of the substrate, and an electrically resistive layer disposed on the first surface of the substrate. The substrate may comprise a compliant electrically insulating and thermally conductive material including a polymeric matrix phase and a dispersed phase of thermally conductive particles. The conductive layer may be patterned into a first electrode and a second electrode spaced apart from the first electrode on the first surface of the substrate. The resistive layer may be in electrical contact with the first and second electrodes of the conductive layer and may comprise a resistive material having a positive resistance temperature coefficient and a resistance that increases with an increase in temperature.

    Abstract: An automotive battery module with numerous battery cells and a series-based cooling fin arrangement placed in thermal communication with at least two of the battery cells. Heat generated within the battery cells by, among other things, electric current that can be used to provide motive power for the automobile, may be removed by the cooling fin that includes different portions tailored to remove relatively lesser or greater amounts of heat, depending on a potential temperature difference among the cells. The construction of the cooling fin is such that multiple heat transfer paths are established, each configured to convey heat away from the battery cells, as well as to keep temperature differences between adjacent series-cooled battery cells to a minimum. In one form, the multiple heat transfer paths may include a relatively laminar portion and a relatively turbulent portion, where in one form the increased turbulence may be obtained through numerous turbulators. Other such heat transfer paths may include an intermediate exhaust path, a discreet coolant channel or the like. Any or all of the turbulators, exhaust path or discreet coolant channel may be tuned in order to increase or decrease an amount of heat delivered to the cooling fin from the battery cells.

    Abstract: A cooling system for a battery pack includes a fluid source for providing cooling fluid and a turbulator in which the cooling fluid flows along an average flow direction. The turbulator includes a first support member, a second support member, a third support member, a first plurality of rods positioned between the first support member and the second support member, and a second plurality of rods positioned between the second and the third support members. The first plurality of rods is offset from the second plurality of rods in a direction perpendicular to the average flow direction. Finally, the first plurality of rods and the second plurality of rods disrupt fluid flow from the fluid source into non-laminar flow.
